Locomotive hom hais txog cov qauv sib txawv ntawm cov locomotives nyob rau hauv tib pawg traction. Nws muaj kev cuam tshuam loj heev rau kev thauj mus los hauv kev tsheb ciav hlau, kev khiav haujlwm ceev, kev ua haujlwm, thiab kev tsim vaj tsev thiab kev thauj mus los. Txij li thaum xyoo 1980, Tuam Tshoj txoj kev lag luam locomotive tau ntsib kev txhim kho tseem ceeb. Lub tshuab hluav taws xob ua haujlwm tau tso tseg, thaum lub zog siab - lub zog hluav taws xob thiab diesel locomotives tau tsim sai heev, ua rau 4, 6, 8, thiab 12- qag series thiab B-B, B0-B0, B0-B0-B0, C0-C0(B), 20-C0(B) thiab configuration series (B thiab C sawv cev rau ob-qag thiab peb-qag bogies feem, thiab 0 qhia hluav taws xob kis tau tus mob). Cov neeg caij tsheb thiab cov tsheb thauj khoom muaj lub zog ntawm 900kW thiab 800kW rau lub tshuab hluav taws xob, thiab 613kW thiab 532kW rau diesel locomotives, feem. Lub traction thiab dynamic braking kev ua tau zoo ntawm locomotives tau zoo heev.
Kev txhim kho thev naus laus zis hauv kev lag luam locomotive tau tsim cov khoom siv hauv paus rau kev xaiv cov hom locomotive hauv kev tsim tsheb ciav hlau kom hloov mus rau cov qauv kev sib tw thiab kev sib tw ntev, txhim kho tsheb ciav hlau qhov hnyav, ceev, thiab ceev, optimizing qhov sib xyaw ntawm peb yam, ua tau raws li cov kev xav tau ntawm kev thauj mus los sib txawv, thiab paub txog cov qauv kev txiav txim siab loj ntawm txoj kev tsheb ciav hlau {{0} kev txhim kho txoj kev tsheb ciav hlau. kev sib piv ntawm cov khoom siv txawb thiab ruaj khov.
